There are enormous pillars positioned in specific places in each of the eight sectors. These pillars are used to hold up gigantic plates far above the various sectors. What's on top is of no true importance, but if you must know for knowledge's sake, there is a huge city up above with people actually living on these plates. Trains run up there and life is generally much better than living down below. Should one of these pillars crumble or give way, an entire sector of the city would be destroyed, slums and all. The Sector 7 Pillar is a place Protega has had to visit before in order to stop Heartless and Nobodies in the past, and they will most likely have to continue doing so far into the future.
